What is in the tank?
That will help with the correct answer. IMO that is not enough even for fish only. If you have any corals then you could be way under. 20 times is 1500 and that would min for FO. Shot for 3000gph for soft corals and go with 4500 or more for hard corals.
I currently have just over 3000gph for a 90gal and am waiting on my sieo 1500.

Your return pump should be used for filteration. If you go with a bigger pump you may have to much flow for your over flow, or the water in sump may move too fast.
So, in your flow calculation do not include return pumps or skimmers.
In a FO tank the biggest thing is making sure the flow keeps particles suspended in the water column so they can be fotered out. If you have low flow the food and poo will settle on bottom and next thing you will have either an algea/cynobacteria break out.
Take a small dowel rod and tie a ribbon on it. Then put it in your tank to actually se the flow pattern in your tank.
You will be amazed at how little there is once you move away from the P/Hs. water is very heavy and puts up a lot of resistance.

Imho and not to contridict the preceeding you will do fine with a turn over rate of 10 to 12 times. I have a 700 gph return pump and a number 3 korilla power head and have not had any issues and lots of flow.
Point proven
